Responses of female rhesus macaques to an environmental enrichment apparatus

The apparatus consisted of a box attached to the monkey's home cage that contained a radio and a food dispenser, which could be controlled by the monkeys via contact detectors.

Social housing of a timed-mating rhesus monkey colony

Even though fighting was a problem in group-housed animals, the fertility rate was approximately 45%. These results indicate that timed-mating may be performed successfully within socially [grouped] housed macaques.

Advances in the management of primates kept for biomedical research

Changes in the management of colonies of long-tailed macaques and common marmosets kept at the Royal College of Surgeons Research Establishment are outlined. These developments are discussed in the context of increasing concern over the need to house and manage...

Using computer games for environmental enrichment for rhesus monkeys in space flight and in the vivarium

It is proposed that a computer based food reward system resembling a computer game mimicas foraging that occurs in the wild, thus presumably relieving boredom.

Living continuously with a compatible companion is not a distressing experience for rhesus monkeys

Paired females had serum cortisol concentrations that did not differ from single-housed females. Dominant animals had cortisol concentrations that did not differ from those of their subordinate companions, indicating that neither dominant nor subordinate partners experienced social distress.

Cortisol response of female rhesus monkeys to venipuncture in homecage versus venipuncture in restraint apparatus

All subjects were well habituated to blood collection, and it was not necessary to immobilize them; they readily presented a leg for venipuncture. In single monkeys venipunctured in the restraint apparatus, cortisol concentrations were on average 50% higher 15 minutes...

Training stumptailed monkeys to cooperate during in-homecage treatment

One to 14 training sessions, each lasting for 1-5 minutes, were required to train adult, pair-housed and single-housed stump-tailed macaques of both sexes to cooperate during topical treatment in the homecage.

Time budget of caged rhesus monkeys exposed to a companion, a PVC perch and a piece of wood for an extended time*

Sixty animals were continuously exposed for at least 1.5 years to a compatible companion for social interaction, a suspended plastic pipe for perching, and a branch segment for gnawing. ... Individuals spent an average of 23.5% of the time interacting...

Social enrichment for laboratory primates: A critical review

23% (54/237) of individually caged, but only 10% (38/382) of pair-housed rhesus monkeys required medical treatment. A photograph shows a compatible pair of adult males who have been reared as social isolates.
